There once was a movie called Great White, which featured a scene in
which a great white shark plows into a windsurfing regatta and shreds
the shredders (sorry!)
The film was said to be such a rip-off of Jaws that it was kicked out
of movie theaters the same week it was released. Also, it never was
made into a home video.
The trailer has appeared, though:
